Titan Motorsports has partnered with industry leading fastener manufacturer ARP to develop an upgraded crank bolt kit for the Toyota 2JZ engine. These upgraded units are manufactured using ARP 2000 material which offers a tensile strength of 220,000 PSI, over 45% stronger than the factory specified Grade 8 bolt. This increase in material strength is partnered with an oversized washer which is both thicker and larger in diameter to take advantage of the increased clamping load and to properly secure the damper to the crank over a larger surface area.
The additional clamp load delivered helps secure the harmonic damper to the crankshaft allowing it to function as designed, absorbing the unwanted kinetic energy caused by undesired movement of the crankshaft. This reduces the risk of the damper loosening from the crankshaft that can occur in racing environments where high RPMs are the norm. This bolt kit is designed to work with the OEM crank pulley, however we recommend it be paired with our Titan Motorsports Crank Damper to offer the ultimate in protection for your engine.

It’s no secret, we build a lot of 2JZ engines, typically we get quite a few email inquiries for advice that typically start like this
“Do I really need this part for my build”
“So and So said that they don’t have this part and it’s a waste of money”
“I don’t want to do extra machine work to my engine but want to make 1,500hp”
Every now and then the conversion starts with a nice picture like the one below that is worth well more than 1,000 words.
This particular engine was making north of 900hp with a factory shortblock setup, as you can see the factory mains decided they weren’t up to the task and the customers re-build/upgrade will now include a set of our Titan Billet Main caps.
The Titan Motorsports billet main caps are precision machined from high tensile billet steel. We developed these main caps out of necessity for our 2JZ race program and soon found them to be applicable in most street engines. With the increased boost levels seen in single and larger twin turbo setups, the factory crank pushes down on the caps often leading to stress fractures and cracks. The factory main caps were not designed for the forces required when doubling and tripling the factory horsepower and torque levels. These caps are included in our short block and race engine packages and now available separately for those building their own engines.
Titan Motorsports main caps will work with both the 2JZ-GTE engine found in the Supra turbo, as well as the 2JZ-GE engine found in non-turbocharged models. Please keep in mind that a line bore of the mains will need to be completed upon installation of these upgraded main caps. We recommend using brand new ARP Main studs and fresh bearings when installing the Titan Motorsports main caps.

At Titan Motorsports we have spent years developing the popular 2JZ engine and experienced plenty of parts failures both big and small. In our quest to creating reliable horsepower with the 2JZ platform we are constantly developing parts to solve these problems as they occur. One such common issue is the timing pickup will often twist from the main timing belt gear causing a trigger error and preventing the engine from properly syncing. We modify the OEM Toyota Timing Pulley to Titan Motorsports specifications to solve this problem and fortify this connection. Starting with a brand new factory Toyota timing gear, we carefully stitch weld the timing pickup sensor to the main gear locking them in place permanently and preventing slippage.
This gear is sold as a complete unit that is based off a brand new core part from Toyota, as a result there is no core charge required.
